How are humans affected when their eyes are opened and their faith is tested?

This Is a religious question, I would say that most people believe in God and this affects how they live there everyday life. Not everyone believes in the same religion, so there are going to be people that test your faith and your eyes and going to be opened to the people around you are there religions, but also it will open your eyes to dig a little deeper into learning more about your faith, so you can stand strong when others test you.
